Actually wasn't the Infinity Coaster given the option of having a lap bar option yet Merlin went with OTSR?
Honestly, there is a great ride in there that is screaming to get out much like Goudruix. If it had the lap bars the roughness we complain about would stop, maybe actually get some respect.
I have said to several that Smiler is just three or four steps away from being a masterpiece, I do love the layout I'll admit, in which those I've said are as follows.
1) The lapbar type cars could help.
2) Having the pit be better designed to have cuttings in which the ride flies through rather than just a sea of flat concrete.
3) The theming ofc, as much as we can say it's poor, belive it or not it could have been worse had they gone for the original planned abandoned hospital theme though budget cuts put an end to that. What I mean by that is that when we had so many spooky/abandoned themes from Merlin like Thirteen, Swarm and Saw, I'm kinda glad we never got that for Smiler as it would have looked even more out of place from X-Sector. Yes, the final theme on Smiler may look sanitised and clean (before it got rusty as of now) but at the very least somewhat blends into the area a little better...honestly one of the rare times IMO that budget cuts for theming actually
worked. Anyway to get back on topic, I would have liked the station to have a matching curved structure to complement Oblivion's station which would blend seamlessly into X-Sector rather than looking like a Soviet era tower block. Also the second lift hill could be have a tube structure built around it (laughing gas tube anyone) with some sfx smoke and sprial lighting to give a nice wee effect, still wish they brought back the original effects within the indoor bit when it first opened though, when it worked it was great.
4) Also to help with the throughput, I felt that they made a mistake of not building in a second loading area much like with Oblivion, there is space there if you look at the station which honestly could just fit in a second loading area for had they done this or ever did decide to redo this area then Smiler's throughput levels would improve considerably, maybe even get all five trains back on again you could potentially get away with again.
So yeah, a flawed ride but I do have a soft spot for it but I'll admit it can be improved in places. Also, I can happily say that I'm fairly fortunate that I have managed to have fairly smooth rides on it whenever I visit, old girl seems to like me as I'm a fairly tolerant and fair person!
Also, I have learnt techniques how to manage a smooth ride that I manage for the most part to avoid having a head bang.
